Details of the carburetor engine power system:

1 - carburetor; 2 - warm air intake; 3 - cold air intake; 4 - thermostat; 5 - air filter housing cover; 6 - filter element; 7 - air filter housing; 8 - sensor for level indicator and fuel reserve; 9 - fuel tank; 10 - ventilation hose; 11 - filler pipe; 12 - fuel line; 13 - fuel hose; 14 - fuel filter; 15 - fuel pump

The power supply system consists of a fuel tank with a level indicator sensor and a fuel reserve, fuel lines, a fuel pump, an air filter and a carburetor.

The fuel tank is welded from two halves stamped from leaded sheet steel. Outside the tank is painted with black enamel.

On the VAZ-2104 car, a 42-liter fuel tank is installed, which is located under the floor of the luggage compartment on the left side. Tank filler neck

displayed in a niche on the left rear wing. The tank is attached to the bottom of the body with four bolts. For ventilation, the fuel tank has a hose leading into the niche of the filler neck. On top of the tank through the sealing gasket is installed level indicator and fuel reserve sensor. From the sensor on the instrument panel displays data on the remaining fuel in the tank. When there is 4.0-6.5 liters of fuel left, the control lamp on the instrument panel lights up. Fuel lines made of galvanized steel tubes and fixed from below to the bottom of the body with holders. The parts of the fuel system are interconnected by rubber hoses, secured with clamps.

Fuel Pump Details:

1 - lower body; 2 - return spring; 3 - stock; 4 - plate diaphragm assembly; 5 - safety diaphragm; 6 - internal spacer; 7 - working diaphragms; 8 - outer spacer; 9 - pump cover; 10 - mesh filter; 11 - upper case

The fuel pump is a diaphragm type, with a mechanical drive and a manual pumping lever. The pump is located on the left side of the cylinder block and is fixed through a heat-insulating spacer and gaskets on two studs with nuts. The pump is driven through a pusher from an eccentric on the auxiliary drive shaft or from a manual pumping lever. The pump capacity is not less than 60 l/h at a pumping frequency of 2000 cycles per minute. The pressure created by the pump is in the range of 0.20-0.30 kgf / cm². The pump consists of a lower housing with drive levers, an upper housing with inlet and discharge valves, a diaphragm assembly and a cover. The diaphragm assembly has two upper working and one lower (safety) diaphragms mounted on the rod. Between the workers and the safety gasket, inner and outer spacers are installed. In order to prevent fuel from entering the crankcase in case of damage to the working diaphragms of the fuel pump, a hole for draining the fuel is made in the outer gasket.

The air filter is dry, with a replaceable filter element that cleans the air entering the carburetor. The filter housing is mounted on the carburetor cover through a rubber gasket with spacer bushings on four studs and fastened with self-locking nuts. The top of the filter housing is closed with a cover with a rubber seal. In the air duct in front of the air filter housing is installed thermostat, allowing you to change the temperature of the incoming air. Depending on one of the three positions of the thermostatic damper, air is drawn in through the warm or cold air inlet, or from both at the same time. The damper position is set manually according to the ambient temperature. The air filter housing is connected by a crankcase gas supply hose to the oil separator cover of the crankcase ventilation exhaust system. A flame arrester is installed in the crankcase gas supply hose.

Carburetor model 2107-1107010 is installed on the car.

Carburetor emulsion type, two-chamber, with a falling stream. The combustible mixture is formed from the air entering through the air filter and the fuel supplied by the pump. This ensures uninterrupted supply of a combustible mixture of optimal composition in all engine operating modes. The prepared mixture is sucked through the inlet pipeline into the engine cylinders. The carburetor consists of three body parts: a cover, a carburetor body and a throttle body.

The carburetor is mounted on four intake pipe studs. In the carburetor cover there are inlet mouths of the primary and secondary mixing chambers, a fuel supply fitting from the fuel pump, fuel and air channels. The cap also has a fuel needle valve and a float attached to ensure the correct fuel level in the float chamber. The carburetor body has large diffusers and a float chamber. Removable small diffusers are installed inside the large diffusers, molded integrally with the atomizers of the econostat and the main dosing systems. Air and fuel channels are made in the carburetor body, air and fuel jets and an accelerator pump sprayer are installed.

Carburetor cover and body:

1 - throttle body; 2 - heat-insulating spacer; 3 - housing of the fuel jet of the transition system of the secondary chamber; 4 - carburetor body; 5 - plug of the carburetor fuel filter; 6 - fuel fitting; 7 - needle valve body; 8 - float; 9 - gasket; 10 - carburetor cover; 11 - air damper lever; 12 - rod connecting the air damper lever with the diaphragm rod of the starting device; 13 - thrust connection of the throttle valve with the drive of the starting device; 14 - lever limiting the opening of the throttle valve of the secondary chamber; 15 - throttle actuator lever; 16 - throttle valve of the primary chamber; 17 - throttle valve of the secondary chamber; 18 - screw for fastening the throttle body; 19 - accelerator pump drive cam

The accelerator pump provides an additional portion of fuel to the primary mixing chamber when the gas pedal is pressed sharply. The diaphragm type pump is made in the tide of the body and is closed with a lid fixed with four screws. The diaphragm of the pump is moved by a lever. To ensure a smooth ride and, accordingly, a smooth and long injection, a damping spring is installed in the telescopic cup of the diaphragm. The accelerator pump lever is driven by a cam mounted on the throttle valve axle of the primary chamber.

From below, the throttle body is attached to the carburetor body with two screws. In it, rotary throttle valves are installed on the axles in the primary and secondary mixing chambers. The drive of the throttle valve of the primary chamber is carried out mechanically through a system of adjustable rods from the "gas" pedal. The drive of the throttle valve of the secondary chamber is pneumatic. The drive housing, with a diaphragm and a return spring, is fixed to the carburetor body with two screws. The drive rod is pivotally connected to the lever on the axis of the throttle valve of the secondary chamber. The pneumatic drive begins to open it when the throttle valve of the primary chamber is deflected by an angle of more than 48° and a vacuum is created in the mixing chambers sufficient to open the damper.

To start and operate the engine when warming up, the carburetor has a starting device and an air damper. The air damper is mounted on an axis in the inlet neck of the primary chamber of the carburetor cover. The damper is driven from the driver's seat by a cable from the control handle. The body of the starting device is fastened with two screws to the carburetor cover. The diaphragm rod of the starter drive is connected by a rod to the air damper lever. The starting device cavity is connected by an air channel to the primary mixing chamber. When the engine starts, a vacuum is created in the cavity. The diaphragm rod depresses the return spring, acts on the thrust and slightly opens the air damper.

Carburetor body:

1 - microswitch bracket; 2 - small diffuser of the primary chamber; 3 - three-arm lever; 4 - accelerator pump sprayer; 5 - small diffuser of the secondary chamber; 6 - main air jet of the secondary chamber; 7 - main air jet of the primary chamber; 8 - main fuel jet of the secondary chamber; 9 - main fuel jet of the primary chamber; 10 - adjusting screw for fuel supply by the accelerator pump; 11 - housing of the fuel jet of the idle system; 12 - adjusting screw of the composition (quality) of the mixture at idle; 13 - fitting for supplying vacuum to the vacuum regulator of the ignition distributor; 14 - adjusting screw for the amount of mixture at idle with a restrictive sleeve

Idling adjustment is carried out by screws of the composition (quality) and the amount of the mixture. The composition adjustment screw is installed in the lug hole of the throttle body and is closed with a plug. The mixture adjustment screw is installed in the economizer cover.

The opportunities that open up for the car owner allow you to transform any car, make it even better than it was before. Owners of domestic cars are also actively interested in such opportunities and actively apply them in practice. Today we will consider, we will analyze possible options that can be put into practice.

Body transformation

In the process of tuning the famous "four" from VAZ, the greatest attention is paid to changing the body. Its design is no longer considered attractive and modern, now this angular form looks outdated and unattractive. It is possible in several options, which differ in cost and scope of work:

1. easy is to replace the radiator grille, tinted windows, install discs on the wheels and skirts "Vihur";
2. with an average body tuning, it will be necessary to install alternative optics, replace the body kit, think about the possibility of ordering professional airbrushing and shaving, which consists in removing handles, locks and moldings;
3. deep, as you might guess, is the most difficult, expensive and time-consuming, since it requires changes in the body structure, for example, changing the roof level, altering the coupe, installing lambo doors.

Even an easy tuning option will transform the appearance of the car. Sparkling chrome on the body, solid tinted windows, rare or, conversely, ultra-modern wheel covers - and your car will already look worthy on the road.

Changing the body structure

And if you take a more serious approach to the transformation of a domestic car and decide to “truncate” the body, then you can get a small-sized car that can be deftly drifted and easily maneuvered. To get such a powerful baby, it is necessary to remove part of the passenger compartment and reduce the length of the driveshaft. Hoping for significant fuel savings is not worth it, consumption will decrease, but not as significantly as we would like. Now you need to do electrical wiring, shift the brake lines, carefully close everything and repaint. Another cardinal decision is to move the spare wheel to the trunk lid. But such a design, as they say, is not for everybody.

The body structure can change not only in length, but also in height. Usually, the cabin height is lowered by a maximum of 15 cm. This result can be achieved by cutting the pillars, changing the front bumper, and rear lighting. The exterior in this case changes dramatically. Getting used to such dimensions of the car will not be easy.

If you are lucky enough to ride on perfect asphalt, then you can transform your VAZ-2104 in a rare Stance style. Its essence lies in the installation of short springs and discs of small diameter. A car with such changes is quite rare, so your VAZ-2104 can become a unique instance. A more popular type of tuning is a body lift, which is the opposite of Stance. Such a car can easily overcome bad sections of the road and even off-road.

The controversial point is the need to strengthen the supporting body platforms. This moment cannot be called mandatory, but it is still better if it is implemented. It certainly won't get any worse than this. The installation of stiff springs, which is provided for in the tuning process, requires reinforced metal. For the front suspension, you can choose springs from the Volga, and pick up the rear shock absorbers from the Gazelle front end.

Seriously, you need to think about installing air bags that will not allow the body to sway, and make the move softer. Pneumopillows are installed inside the springs. A similar element can be added to a lifted and standard body, its operation will not change from this.

Coloring

Body painting is an important element in any tuning. Still, this parameter is most striking and is able to highlight any car. There are several ways to solve this problem. You can go the standard way and cover the body with ordinary paint with an interesting effect (metallic, chameleon, matte, glossy). One of the new solutions is liquid rubber. Such coloring will not only make the tuned car expressive, but also protect the body from external influences. Airbrushing can be used not only on expensive foreign cars, but also on models of the domestic auto industry. It is better to entrust such coloring to specialists who have extensive experience in this field and can transfer any fantasy to metal. Airbrushing requires compliance with the declared status, and if you have already chosen this method of transformation, then a clumsy roof rack, old wheels or a rusty trailer will make the car ridiculous and tasteless.

Internal changes

Inside the car, you will need to do as much work as outside. By we mean pumping the engine, replacing the brake system and modifying the interior. But first things first.

Engine and brakes

Tuning domestic cars is embodied not only in external changes, but also in internal ones. Believe me, under the hood, a lot of parts need reorganization or complete replacement. The main element of any car - the engine - is primarily subject to tuning. If your car has a native power unit that has faithfully worked out its due date, then it is better to send it to a well-deserved rest, that is, to scrap metal. Still, the metal is rather tired, and even physical deterioration takes place - these factors do not allow us to talk about further refinement and forcing. There is only one conclusion - the old engine, which unscrewed several circles of the speedometer, must be replaced, and you can still work on newer units.

A worthy replacement for the old engine will be a powerful unit taken from the VAZ-21213, its volume will be 1900 cm3. Its power can be increased from 79 to 120 horses, but this will require some effort and parting with your hard-earned money. The forcing process consists in boring the channels, grinding the intake manifold, installing cast pistons with a diameter of 82 mm. To change the valve timing, it will be necessary to purchase a new camshaft, with which it will be possible to lift the valves up to 10.8 mm.

When using a sports crankshaft by 88 mm and increasing the level of piston lift, it is possible to increase the volume of the power unit and facilitate the removal of the increased force that occurs during the combustion of the fuel-air mixture.

Installing a lightweight flywheel will reduce the loss of power that is spent on the promotion of the motor. As a result, the car will pick up the required speed in a short time.

The exhaust and power system also need an upgrade, which consists of installing an air filter, a sports exhaust manifold and a straight-through muffler.

It remains to upgrade the brakes, which are responsible for the safety of the driver, his passengers and other road users. Drum brakes, which are available on the rear axle in the VAZ-2104, are difficult to operate, and even not effective enough. Their replacement is mandatory, 13-inch ventilated disc brakes are well suited for this.

Salon change

The effect of all the external changes that have occurred with the VAZ-2104 will be irrevocably spoiled by an outdated interior. is no less important than upgrading the engine and working on the body. Everything here can be very simple. If the seats are in good condition but look worn, you can replace the upholstery. With sufficient funding, you can choose a leather material for upholstery, but any other will also look good. Carbon fiber decor is a great way to enhance the effect of tuning and give the interior a high cost.

Any car can be restored, transformed and improved its previous characteristics. This is especially true for domestic models, for example, the VAZ-2104, although tuning with your own hands requires an investment of money and finances, the result is worth it.

The VAZ 2107 car has long been a legend in the domestic auto industry. Everyone is familiar with its famous body in a classic color with a simple geometry. Being a luxury version of the VAZ 2105, it was produced from 1982 to 2012 in several modifications, had various configurations, including a pickup truck.

What is a body

The body is one of the most important structural elements of a car. It is attached to the frame, but there are also frameless designs. The body is designed to accommodate passengers and cargo. There are also structures designed to transport laboratory, medical or other special equipment.

Depending on the device, the bodies are frame, frameless and semi-frame.

car body

The body of the VAZ 2107 is a rear-wheel drive four-door sedan. The assembly scheme of its frame is standard and has the following elements:

• front parts;
• Front fenders with amplifiers;
• Roofs with glass frames;
• Floor with reinforcements and back panel;
• Side parts;
• Rear fenders.

Each element is cast from mild steel. Each part has not only its own number, casting scheme, but also its own thickness. For example, 0.9 mm for the roof, and 1.0 mm for the rear wheel arches.

Most of the parts are connected using non-contact welding, but parts that carry a large load are additionally strengthened by arc welding.

Among the hinged parts it is worth highlighting:

1. hood;
2. doors;
3. trunk lid;
4. bumpers.

Machine detail diagram

The bumper elements are made of plastic, attached with brackets, and have chrome lining.

Inside the car is quite spacious. The front seats have adjustable backrest and fore/aft position. The back seat is three-seater.

All glasses are of a safe type, and the well-thought-out structure of the car will reduce the impact in an accident.

Dimensions and Specifications

Regardless of the configuration, the VAZ 2107 has the following dimensions:

- length - 4126,

- width - 1620,

- height - 1435.

- curb weight (how much is the weight of a car with equipment and materials) - 1030 kg,

- gross weight (how much the equipped car weighs with passengers and cargo) - 1430 kg

The motorist needs to know not only the standard parameters of his car, but also the control dimensions.

Control dimensions (points) are usually necessary when restoring a car after an accident. If you buy a used car, knowing such control dimensions, you can easily find out if the car has been in an accident. This geometry will help in the restoration of the body, as well as other important details.

The main control dimensions are described in detail by the diagram below:

Linear dimensions are clearly defined by the following scheme:

Identification data

Auto VAZ 2107, like any other car, has specific passport data, the liver of which is indicated in the table located under the hood on the air drive box.

The plate contains information about the model of the machine, engine number and body number, weight data and spare part number. Above it is the vehicle identification number - VIN.

- The first 3 letters are responsible for the manufacturer's code;

- 6 subsequent digits are the decoding of the car model;

- A letter or number of the Latin alphabet indicates the year of manufacture of the VAZ 2107 model;

- The last 7 digits - this is the desired body number.

Exactly the same number you will find in the trunk.

Options and modifications

For buyers, the VAZ 2107 was available in the following trim levels:

— in a complete set "standard";

— in a complete set "norm";

- in the deluxe package.

The car has always been produced in 10 modifications both for Russia and for foreign countries.

The famous pickup

For those who were looking for a spacious, convenient option, a pickup truck of any color was produced on the basis of the VAZ 2107. It is called the pickup truck VIS - 2345, but is no longer produced either. But despite this, it is still popular.

This subcompact pickup truck is easy to drive, giving you plenty of room to haul as many things as you need. Even a refrigerator will fit in a wide isothermal booth.

The double pickup has an injection engine. It develops speed up to 110 km/h. Due to the convenience and original design, this body type is very common in America and Europe - so it is a pity that the production of this model was stopped.

Body replacement

The VAZ 2107 car in sedan or pickup bodies has not been produced for several years, but drivers can still purchase bodies for their cars if necessary. If suddenly you got into an accident, or the body of your car is in disrepair, you can easily order a new one.

The action plan is simple. To begin with, you will need to decide on the necessary equipment, as well as what type of body you need.

One package includes a new "body assembly", which includes electrical appliances, wiring, windows, front and rear bumpers;

The other equipment is called "body in metal". It includes a new body painted with paint of the desired color, treated with anti-corrosion preparations.

The plant provided a variety of colors for the VAZ 2107 car. Each of them has its own name. For example, pale yellow is “melon”, classic red is “viburnum”, and marsh green is “Sochi”.

When ordering a body in the third configuration, you can make it in any color. It may take longer than if you settled on plain white paint. But a car with a bright, conspicuous color will always be a pleasure to drive.

VAZ 2104- Soviet passenger car with a station wagon body type, developed at the VAZ plant. Serially produced from 1984 to 2012. The model was developed as a replacement for the outdated station wagon 2102. For some time, 2102 and 2104 were produced at the factory in parallel. When creating a new model, the plant took the path of least cost and used the VAZ 2105 as the base model. All spare parts underwent maximum unification. To give rigidity, stampings appeared on the roof of the new model. Unlike the 2102 model, the rear window heating was installed on the "four" in the basic configuration. From the mid-1990s, a rear wiper will be included as standard. The base model received the interior from the 2105. The station wagon's payload capacity was 455 kg, nearly double the maximum payload of the 2102. The model inherited the tailgate design from its predecessor. Its edge coincided with the floor level, which facilitated the loading and unloading of luggage. The rear seat folds down to create a huge loading area.

Modifications of the VAZ-2104

The following models were produced: - 21041, 21043 and 21043-07, differing in engines of 1.2 liters, 1.5 liters and a "seven" interior, respectively. In 1994, the VAZ-2104 with a 1.3-liter engine was discontinued. Today, the VAZ 21043 with a 1.5-liter engine and a five-speed manual gearbox has become the base model, which makes the VAZ 21043 AW car more dynamic and enjoyable to drive. Not so long ago, a modification of the VAZ-21045 appeared with an atmospheric (non-aspirated) diesel engine manufactured by Barnaultransmash, with a volume of 1.52 liters.

Interior design and controls

Generally design model VAZ-2104, like all classical models, ascetic. But the interior of the car, depending on your desire, may be different. A more economical option involves a standard panel with the minimum necessary set of switches and instrumentation, upholstery and seats with standard artificial leather headrests, rubber floor mats. If you want more comfort, then you are offered an improved interior, original steering wheel and instrument panel with an additional center console, which has an expanded set of function keys and control equipment. The improved salon is seats upholstered in brushed knitwear (front with a high back), doors with integrally molded overlays, brushed floor mats. This version of the "four" will allow you to feel comfortable even on a long trip.

VAZ-2104 engine and its features

Engine 2104-1000260 can be used for installation on VAZ 2103, 2104, 2106, 21053, 2107 vehicles.
Initially, the VAZ 2104 engine was produced only in a carburetor version. Later it was modified to use a fuel injection system and received the designation VAZ 2104-21.
The VAZ 2104 engine was created on the basis of the previous model - the VAZ 2103. The design used: a cylinder block, a connecting rod and a piston group, a timing drive and a crankshaft from the 2103 engine.

photo engine VAZ-2104

Cylinder block from the VAZ 2103 engine. Cylinder diameter - 76.00 mm. Accepted overhaul dimensions - 76.40 and 76.80. The engine is fitted with a 2103 crankshaft or an interchangeable 21213 crankshaft.
To ensure the operation of the injection system, it was necessary to install components and parts from other engines, which were originally developed for the fuel injection scheme. A new camshaft drive cover is used, on which there is a place for installing a sensor that controls the position of the crankshaft. It was required to install the cylinder head 2104-1003015, of the original design, with enlarged areas for the intake manifold. The design of the head provides for the installation of nozzles. The camshaft, valves and springs correspond to those installed on the VAZ 2103 engine. Installation of valve lever hydraulic bearings is not provided.
The timing drive is carried out from a two-row bush-roller chain 2103-1006040. The chain tensioning mechanism is mechanical, similar to the device on the VAZ 2103 engine.

A pulley with a damper and a drive disk 21214-1005058-11 is installed on the crankshaft. To drive the generator, a belt 2107-1308020 is used (length - 944mm). Injector modification 2104 has an original power supply system. The system includes an electric fuel pump with a fuel gauge sensor, fuel lines, a fuel filter, a fuel rail with injectors, an air filter, air supply hoses, a throttle valve and a fuel vapor recovery system. To clean the air entering the engine, a model 2112 air filter is provided. A model 2104 or model 2123-1008027 receiver is installed with the intake manifold. Throttle pipe 2112 is installed to adjust the volume of incoming air.
The electric fuel pump module 21073-1139009 is installed in the tank and provides fuel supply to the fuel rail and injectors. Used original fuel rail 2104-1144010, box type with pressure regulator and return drain line. Injection is carried out using four nozzles in pairs and parallel action. It is possible to install injectors BOSCH 0 280 158 502 (black, thin), SIEMENS VAZ 6393 (beige, thick) or other types with appropriate parameters.
The ignition system includes: a model 2112 ignition module mounted on a special bracket on the cylinder block, spark plugs and high voltage wires. The ignition module contains two ignition coils and two electronic controls. In accordance with the control signals from the control unit, the ignition module generates and supplies high-voltage pulses to the spark plugs.
Ignition control is assigned to the electronic engine management system. This system provides control of the amount of air and fuel supplied to the cylinders, controls the operation of the fuel pump, controls the supply of high-voltage pulses from the ignition coil to the spark plugs and corrects the ignition timing, regulates the idle speed of the crankshaft. The main control element of the system is the electronic control unit (ECU)-controller.
The engine complies with EURO-2 toxicity standards.
